Research & Publications
My research involves the application of biostatistics to psychiatric research, both clinical and epidemiological. I am primarily interested in latent variable methods, including latent class analysis and growth mixture models which allow for the modeling of risk factors, treatment response, or outcomes as a function of latent class membership based on patterns of symptoms or shapes of trajectories over time.
